Part II: EMC Evolves Enterprise Data Protection with Enhancements

Storage I/O trends

This is the second part of a two-part series on recent EMC backup and data protection announcements. Read part I here.

What about the products, what’s new?

In addition to articulating their strategy for modernizing data protection (covered in part I here), EMC announced enhancements to Avamar, Data Domain, Mozy and Networker.

Data protection storage systems (e.g. Data Domain)

Building off of previously announced Backup Recovery Solutions (BRS) including Data Domain operating system storage software enhancements, EMC is adding more application and software integration along with new platform (systems) support.

Data Domain (e.g. Protection Storage) enhancements include:

  • Application integration with Oracle, SAP HANA for big data backup and archiving
  • New Data Domain protection storage system models
  • Data in place upgrades of storage controllers
  • Extended Retention now available on added models
  • SAP HANA Studio backup integration via NFS
  • Boost for Oracle RMAN, native SAP tools and replication integration
  • Support for backing up and protecting Oracle Exadata
  • SAP (non HANA) support both on SAP and Oracle

Data in place upgrades of controllers for 4200 series models on up (previously available on some larger models). This means that controllers can be upgraded with data remaining in place as opposed to a lengthy data migration.

Extended Retention facility is a zero cost license that enables more disk drive shelves to be attached to supported Data Domain systems. Thus there is a not a license fee, however you do pay for the storage shelves and drives to increase the available storage capacity. Note that this feature increases the storage capacity by adding more disk drives and does not increase the performance of the Data Domain system. Extended Retention has been available in the past however is now supported via more platform models. The extra storage capacity is essentially placed into a different tier that an archive policy can then migrate data into.

Boost for accelerating data movement to and from Data Domain systems is only available using Fibre Channel. When asked about FC over Ethernet (FCoE) or iSCSI EMC indicated its customers are not asking for this ability yet. This has me wondering if it is that the current customer focus is around FC, or if those customers are not yet ready for iSCSI or FCoE, or, if there were iSCSI or FCoE support, more customers would ask for it?

With the new Data Domain protection storage systems EMC is claiming up to:

  • 4x faster performance than earlier models
  • 10x more scalable and 3x more backup/archive streams
  • 38 percent lower cost per GB based on holding price points and applying improvements


EMC Data Domain data protection storage platform family


Data Domain supporting both backup and archive

Expanding Data Domain from backup to archive

EMC continues to evolve the Data Domain platform from just being a backup target platform with dedupe and replication to a multi-function, multi-role solution. In other words, one platform with many uses. This is an example of using one tool or technology for different purposes such as backup and archiving, however with separate polices. Here is a link to a video where I discuss using common tools for backup and archiving, however with separate polices. In the above figure EMC Data Domain is shown as being used for backup along with storage tiering and archiving (file, email, Sharepoint, content management and databases among other workloads).


EMC Data Domain supporting different functions and workloads

Also shown are various tools from other vendors such as Commvault Simpana that can be used as both a backup or archiving tool with Data Domain as a target. Likewise Dell products acquired via the Quest acquisition are shown along with those from IBM (e.g. Tivoli), FileTek among others. Note that if you are a competitor of EMC or simply a fan of other technology you might come to the conclusion that the above may not be different from others. Then again others who are not articulating their version or vision of something like the above figure probably should be also stating the obvious vs. arguing they did it first.

Data source integration (aka data protection software tools)

It seems like just yesterday that EMC acquired Avamar (2006) and NetWorker aka Legato (2003), not to mention Mozy (2007) or Dantz (Retrospect, since divested) in 2004. With the exception of Dantz (Retrospect) which is now back in the hands of its original developers, EMC continues to enhance and evolve Avamar, Mozy and NetWorker including with this announcement.

General Avamar 7 and Networker 8.1 enhancements include:

  • Deeper integration with primary storage and protection storage tiers
  • Optimization for VMware vSphere virtual server environments
  • Improved visibility and control for data protection of enterprise applications

Additional Avamar 7 enhancements include:

  • More Data Domain integration and leveraging as a repository (since Avamar 6)
  • NAS file systems with NDMP accelerator access (EMC Isilon & Celera, NetApp)
  • Data Domain Boost enhancements for faster backup / recovery
  • Application integration with IBM (DB2 and Notes), Microsoft (Exchange, Hyper-V images, Sharepoint, SQL Server), Oracle, SAP, Sybase, VMware images

Note that Avamar dat is still used mainly for ROBO and desktop, laptop type backup scenarios that do not yet support Data Domain. Also see Mozy enhancements below).

Avamar supports VMware vSphere virtual server environments using granular change block tracking (CBT) technology as well as image level backup and recovery with vSphere plugins. This includes an Instant Access recovery when images are stored on Data Domain storage.

Instant Access enables a VM that has been protected using Avamar image level technology on Data Domain to be booted via an NFS VMware Dat. VMware sees the VM and is able to power it on and boot directly from the Data Domain via the NFS Dat. Once the VM is active, it can be Storage vMotion to a production storage VMware Dat while active (e.g. running) for recovery on the fly capabilities.


Instant Access to a VM on Data Domain storage

EMC NetWorker 8.1 enhancements include:

  • Enhanced visibility and control for owners of data
  • Collaborative protection for Oracle environments
  • Synchronize backup and data protection between DBA and Backup admin’s
  • Oracle DBAs use native tools (e.g. RMAN)
  • Backup admin implements organizations SLA’s (e.g. using Networker)
  • Deeper integration with EMC primary storage (e.g. VMAX, VNX, etc)
  • Isilon integration support
  • Snapshot management (VMAX, VNX, RecoverPoint)
  • Automation and wizards for integration, discovery, simplified management
  • Policy-based management, fast recovery from snapshots
  • Integrating snapshots into and as part of data protection strategy. Note that this is more than basic snapshot management as there is also the ability to roll over a snapshot into a Data Domain protection storage tier.
  • Deeper integration with Data Domain protection storage tier
  • Data Domain Boost over Fibre Channel for faster backups and restores
  • Data Domain Virtual Synthetics to cut impact of full backups
  • Integration with Avamar for managing image level backup recovery (Avamar services embedded as part of NetWorker)
  • vSphere Web Client enabling self-service recovery of VMware images
  • Newly created VMs inherit backup polices automatically

Mozy is being positioned for enterprise remote office branch office (ROBO) or distributed private cloud where Avamar, NetWorker or Data Domain solutions are not as applicable. EMC has mentioned that they have over 800 enterprises using Mozy for desktop, laptop, ROBO and mobile data protection. Note that this is a different target market than the Mozy consumer product focused which also addresses smaller SMBs and SOHOs (Small Office Home Offices).

EMC Mozy enhancements to be more enterprise grade:

  • Simplified management services and integration
  • Active Directory (AD) for Microsoft environments
  • New storage pools (multiple types of pools) vs. dedicated storage per client
  • Keyless activation for faster provisioning of backup clients

Note that EMC enhanced earlier this year Data Protection Advisor (DPA) with version 6.0.

What does this all mean?

Storage I/O trends

Data protection and backup discussions often focus around tape summit resources or cloud arguments, although this is changing. What is changing is growing awareness and discussion around how data protection storage mediums, systems and services are used along with the associated software management tools.

Some will say backup is broke often pointing a finger at a media or medium (e.g. tape and disk) about what is wrong. Granted in some environments the target medium (or media) destination is an easy culprit to point a finger to as the problem (e.g. the usual tape sucks or is dead) mantra. However, for many environments while there can be issues, it is more often than not the media, medium, device or target storage system that is broke, instead how it is being used or abused.

This means revisiting how tools are used along with media or storage systems allocated, used and retained with respect to different threat risk scenarios. After all, not everything is the same in the data center or information factory.

Thus modernizing data protection is more than swapping media or mediums including types of storage system from one to another. It is also more than swapping out one backup or data protection tool for another. Modernizing data protection means rethinking what different applications and data need to be protected against various threat risks.

Storage I/O trends

What this has to do with today’s announcement is that EMC is among others in the industry moving towards a holistic data protection modernizing thought model.

In my opinion what you are seeing out of EMC and some others is taking that step back and expanding the data protection conversation to revisit, rethink why, how, where, when and by whom applications and information get protected.

This announcement also ties into finding and removing costs vs. simply cutting cost at the cost of something elsewhere (e.g. service levels, performance, availability). In other words, finding and removing complexities or overhead associated with data protection while making it more effective.

Some closing points, thoughts and more links:

There is no such thing as a data or information recession
People and data are living longer while getting larger
Not everything is the same in the data center or information factory
Rethink data protection including when, why, how, where, with what and by whom
There is little data, big data, very big data and big fast data
Data protection modernization is more than playing buzzword bingo
Avoid using new technology in old ways
Data footprint reduction (DFR) can be help counter changing data life-cycle patterns
EMC continues to leverage Avamar while keeping Networker relevant
Data Domain evolving for both backup and archiving as an example of tool for multiple uses

Ok, nuff said (for now).

EMC Evolves Enterprise Data Protection with Enhancements (Part I)

Storage I/O trends

A couple of months ago at EMCworld there were announcements around ViPR, Pivotal along with trust and clouds among other topics. During the recent EMCworld event there were some questions among attendees what about backup and data protection announcements (or lack there of)?

Modernizing Data Protection

Today EMC announced enhancements to its Backup Recovery Solutions (BRS) portfolio (@EMCBackup) that continue to enable information and applications data protection modernizing including Avamar, Data Domain, Mozy and Networker.

Keep in mind you can’t go forward if you can’t go back, which means if you do not have good data protection to go to, you can’t go forward with your information.

EMC Modern Data Protection Announcements

As part of their Backup to the Future event, EMC announced the following:

  • New generation of data protection products and technologies
  • Data Domain systems: enhanced application integration for backup and archive
  • Data protection suite tools Avamar 7 and Networker 8.1
  • Enhanced Cloud backup capabilities for the Mozy service
  • Paradigm shift as part of data protection modernizing including revisiting why, when, where, how, with what and by whom data protection is accomplished.

What did EMC announce for data protection modernization?

While much of the EMC data protection announcement is around product, there is also the aspect of rethinking data protection. This means looking at data protection modernization beyond swapping out media (e.g. tape for disk, disk for cloud) or one backup software tool for another. Instead, revisiting why data protection needs to be accomplished, by whom, how to remove complexity and cost, enable agility and flexibility. This also means enabling data protection to be used or consumed as a service in traditional, virtual and private or hybrid cloud environments.

EMC uses as an example (what they refer to as Accidental Architecture) of how there are different group and areas of focus, along with silos associated with data protection. These groups span virtual, applications, database, server, storage among others.

The results are silos that need to be transformed in part using new technology in new ways, as well as addressing a barrier to IT convergence (people and processes). The theme behind EMC data protection strategy is to enable the needs and requirements of various groups (servers, applications, database, compliance, storage, BC and DR) while removing complexity.

Moving from Silos of data protection to a converged service enabled model

Three data protection and backup focus areas

This sets the stage for the three components for enabling a converged data protection model that can be consumed or used as a service in traditional, virtual and private cloud environments.


EMC three components of modernized data protection (EMC Future Backup)

The three main components (and their associated solutions) of EMC BRS strategy are:

  • Data management services: Policy and storage management, SLA, SLO, monitoring, discovery and analysis. This is where tools such as EMC Data Protection Advisor (aka via WysDM acquisition) fit among others for coordination or orchestration, setting and managing polices along with other activities.
  • Data source integration: Applications, Database, File systems, Operating System, Hypervisors and primary storage systems. This is where data movement tools such as Avamar and Networker among others fit along with interfaces to application tools such as Oracle RMAN.
  • Protection storage: Targets, destination storage system with media or mediums optimized for protecting and preserving data along with enabling data footprint reduction (DFR). DFR includes functionality such as compression and dedupe among others. Example of data protection storage is EMC Data Domain.

Read more about product items announced and what this all means here in the second of this two-part series.

Summary, EMC VMAX 10K, high-end storage systems stayin alive

StorageIO industry trends cloud, virtualization and big data

This is a follow-up companion post to the larger industry trends and perspectives series from earlier today (Part I, Part II and Part III) pertaining to today’s VMAX 10K enhancement and other announcements by EMC, and the industry myth of if large storage arrays or systems are dead.

The enhanced VMAX 10K scales from a couple of dozen up to 1,560 HDDs (or mix of HDD and SSDs). There can be a mix of 2.5 inch and 3.5 inch devices in different drive enclosures (DAE). There can be 25 SAS based 2.5 inch drives (HDD or SSD) in the 2U enclosure (see figure with cover panels removed), or 15 3.5 inch drives (HDD or SSD) in a 3U enclosure. As mentioned, there can be all 2.5 inch (including for vault drives) for up to 1,200 devices, all 3.5 inch drives for up to 960 devices, or a mix of 2.5 inch (2U DAE) and 3.5 inch (3U DAE) for a total of 1,560 drives.

Note carefully in the figure (courtesy of EMC) that the 2U 2.5 inch DAE and 3U 3.5 inch DAE along with the VMAX 10K are actually mounted in a 3rd cabinet or rack that is part of today’s announcement.

Also note that the DAE’s are still EMC; however as part of today’s announcement, certain third-party cabinets or enclosures such as might be found in a collocation (colo) or other data center environment can be used instead of EMC cabinets.  The VMAX 10K can however like the VMAX 20K and 40K support external storage virtualized similar to what has been available from HDS (VSP/USP) and HP branded Hitachi equivalent storage, or using NetApp V-Series or IBM V7000 in a similar way.

As mentioned in one of the other posts, there are various software functionality bundles available. Note that SRDF is a separate license from the bundles to give customers options including RecoverPoint.

Check out the three post industry trends and perspectives posts here, here and here.

EMC VMAX 10K, looks like high-end storage systems are still alive (part II)

StorageIO industry trends cloud, virtualization and big data

This is the second in a multi-part series of posts (read first post here) looking at if large enterprise and legacy storage systems are dead, along with what todays EMC VMAX 10K updates mean.

Thus on January 14 2013 it is time for a new EMC Virtual Matrix (VMAX) model 10,000 (10K) storage system. EMC has been promoting their January 14 live virtual event for a while now. January significance is that is when (along with May or June) is when many new systems, solutions or upgrades are made on a staggered basis.

Historically speaking, January and February, along with May and June is when you have seen many of the larger announcements from EMC being made. Case in point, back in February of 2012 VFCache was released, then May (2012) in Las Vegas at EMCworld there were 42 announcements made and others later in the year.

Click here to see images of the car stuffing or click here to watch a video.

Let’s not forget back in February of 2012 VFCache was released, and go back to January 2011 there was the record-setting event in New York City complete with 26 people being compressed, deduped, singled instanced, optimized, stacked and tiered into a mini cooper (Coop) automobile (read and view more here).

Now back to the VMAX 10K enhancements

As an example of a company, product family and specific storage system model, still being alive is the VMAX 10K. Although this announcement by EMC is VMAX 10K centric, there is also a new version of the Enginuity software (firmware, storage operating system, valueware) that runs across all VMAX based systems including VMAX 20K and VMAX 40K. Read here, here and here and here to learn more about VMAX and Enginuity systems in general.

Some main themes of this announcement include Tier 1 reliability, availability and serviceability (RAS) storage systems functionality at tier 2 pricing for traditional, virtual and cloud data centers.

Some other themes of this announcement by EMC:

  • Flexible, scalable and resilient with performance to meet dynamic needs
  • Support private, public and hybrid cloud along with federated storage models
  • Simplified decision-making, acquisition, installation and ongoing management
  • Enable traditional, virtual and cloud workloads
  • Complement its siblings VMAX 40K, 20K and SP (Service Provider) models

Note that the VMAX SP is a model configured and optimized for easy self-service and private cloud, storage as a service (SaaS), IT as a Service (ITaaS) and public cloud service providers needing multi-tenant capabilities with service catalogs and associated tools.

So what is new with the VMAX 10K?

It is twice as fast (per EMC performance results) as earlier VMAX 10K by leveraging faster 2.8GHz Intel westmere vs. earlier 2.5GHz westmere processors. In addition to faster cores, there are more, from 4 to 6 on directors, from 8 to 12 on VMAX 10K engines. The PCIe (Gen 2) IO busses remain unchanged as does the RapidIO interconnect.  RapidIO  used for connecting nodes and engines,  while PCIe is used for adapter and device connectivity. Memory stays the same at up to 128GB of global DRAM cache, along with dual virtual matrix interfaces (how the nodes are connected). Note that there is no increase in the amount of DRAM based cache memory in this new VMAX 10K model.

This should prompt the question of for traditional cache centric or dependent for performance storage systems such as VMAX, how much are they now CPU and their associated L1 / L2 cache dependent or effective? Also how much has the Enginuity code under the covers been enhanced to leverage the multiple cores and threads thus shifting from being cache memory dependent processor hungry.

Also new with the updated VMAX 10K include:

  • Support for dense 2.5 inch drives, along with mixed 2.5 inch and 3.5 inch form factor devices with a maximum of 1,560 HDDs. This means support for 2.5 inch 1TB 7,200 RPM SAS HDDs, along with fast SAS HDDs, SLC/MLC and eMLC solid state devices (SSD) also known as electronic flash devices (EFD). Note that with higher density storage configurations, good disk enclosures become more important to counter or prevent the effects of drive vibration, something that leading vendors are paying attention to and so should customers.
  • EMC is also with the VMAX 10K adding support for certain 3rd party racks or cabinets to be used for mounting the product. This means being able to mount the VMAX main system and DAE components into selected cabinets or racks to meet specific customer, colo or other environment needs for increased flexibility.
  • For security, VMAX 10K also supports Data at Rest Encryption or (D@RE) which is implemented within the VMAX platform. All data encrypted on every drive, every drive type (drive independent) within the VMAX platform to avoid performance impacts. AES 256 fixed block encryption with FIPS 140-2 validation (#1610) using embedded or external key management including RSA Key Manager. Note that since the storage system based encryption is done within the VMAX platform or controller, not only is the encrypt / decrypt off-loaded from servers, it also means that any device from SSD to HDD to third-party storage arrays can be encrypted. This is in contrast to drive based approaches such as self encrypting devices (SED) or other full drive encryption approaches. With embedded key management, encryption keys kept and managed within the VMAX system while external mode leverages RSA key management as part of a broader security solution approach.
  • In terms of addressing ease of decision-making and acquisition, EMC has bundled core Enginuity software suite (virtual provisioning, FTS and FLM, DCP (dynamic cache partitioning), host I/O limits, Optimizer/virtual LUN and integrated RecoverPoint splitter). In addition are bundles for optimization (FAST VP, EMC Unisphere for VMAX with heat map and dashboards), availability (TimeFinder for VMAX 10K) and migration (Symmetrix migration suite, Open Replicator, Open Migrator, SRDF/DM, Federated Live Migration). Additional optional software include RecoverPoint CDP, CRR and CLR, Replication Manager, PowerPath, SRDF/S, SRDF/A and SRDF/DM, Storage Configuration Advisor, Open Replicator with Dynamic Mobility and ControlCenter/ProSphere package.

Who needs a VMAX 10K or where can it be used?

As the entry-level model of the VMAX family, certain organizations who are growing and looking for an alternative to traditional mid-range storage systems should be a primary opportunity. Assuming the VMAX 10K can sell at tier-2 prices with a focus of tier-1 reliability, feature functionality, and simplification while allowing their channel partners to make some money, then EMC can have success with this product. The challenge however will be helping their direct and channel partner sales organizations to avoid competing with their own products (e.g. high-end VNX) vs. those of others.

Consolidation of servers with virtualization, along with storage system consolidation to remove complexity in management and costs should be another opportunity with the ability to virtualize third-party storage. I would expect EMC and their channel partners to place the VMAX 10K with its storage virtualization of third-party storage as an alternative to HDS VSP (aka USP/USPV) and the HP XP P9000 (Hitachi based) products, or for block storage needs the NetApp V-Series among others. There could be some scenarios where the VMAX 10K could be positioned as an alternative to the IBM V7000 (SVC based) for virtualizing third-party storage, or for larger environments, some of the software based appliances where there is a scaling with stability (performance, availability, capacity, ease of management, feature functionality) concerns.

Another area where the VMAX 10K could see action which will fly in the face of some industry thinking is for deployment in new and growing managed service providers (MSP), public cloud, and community clouds (private consortiums) looking for an alternative to open source based, or traditional mid-range solutions. Otoh, I cant wait to hear somebody think outside of both the old and new boxes about how a VMAX 10K could be used beyond traditional applications or functionality. For example filling it up with a few SSDs, and then balance with 1TB 2.5 inch SAS HDD and 3.5 inch 3TB (or larger when available) HDDs as an active archive target leveraging the built-in data compression.

How about if EMC were to support cloud optimized HDDs such as the Seagate Constellation Cloud Storage (CS) HDDs that were announced late in 2012 as well as the newer enterprise class HDDs for opening up new markets? Also keep in mind that some of the new 2.5 inch SAS 10,000 (10K) HDDs have the same performance capabilities as traditional 3.5 inch 15,000 (15K) RPM drives in a smaller footprint to help drive and support increased density of performance and capacity with improved energy effectiveness.

How about attaching a VMAX 10K with the right type of cost-effective (aligned to a given scenario) SSD or HDDs or third-party storage to a cluster or grid of servers that are running OpenStack including Swift, CloudStack, Basho Riak CS, Celversafe, Scality, Caringo, Ceph or even EMCs own ATMOS (that supports external storage) for cloud storage or object based storage solutions? Granted that would be thinking outside of the current or new box thinking to move away from RAID based systems in favor or low-cost JBOD storage in servers, however what the heck, let’s think in pragmatic ways.

Will EMC be able to open new markets and opportunities by making the VMAX and its Enginuity software platform and functionality more accessible and affordable leveraging the VMAX 10K as well as the VMAX SP? Time will tell, after all, I recall back in the mid to late 90s, and then again several times during the 2000s similar questions or conversations not to mention the demise of the large traditional storage systems.

Continue reading about what else EMC announced on January 14 2013 in addition to VMAX 10K updates here in the next post in this series. Also check out Chucks EMC blog to see what he has to say.

Ok, nuff said (for now).

Cloud conversation, Thanks Gartner for saying what has been said

StorageIO industry trends cloud, virtualization and big data

Thank you Gartner for your statements concurring and endorsing the notion of clouds can be viable, however do your homework, welcome to the club.

Why am I thanking Gartner?

Simple, I appreciate Gartner now saying what has been said for a couple of years hoping it will help to amplify the theme to the Gartner followers and faithful.

Gartner: Cloud storage viable option, but proceed carefully

Sounds like Gartner has come to the same conclusion on what has been said for several years now in posts, articles, keynotes, presentations, webinars and other venues which is when it comes to IT clouds, don’t be scared. However do your homework, be prepared, do your due diligence, proof of concepts.

Congratulations Imation and Nexsan, are there any independent storage vendors left?

StorageIO industry trends cloud, virtualization and big data

Last week Imation, the company that is known for making CDs, DVDs, magnetic tape and in the past floppy disk (diskettes) bought Nexsan, a company known for the SATA and SAS storage products.

Imation is also (or should be) owns the TDK and Memorex names (remember is it real or is it Memorex? If not Google it). They also have had for several years removable hard disk drive (RHDD) products including the Odyssey (I am in the process of retiring mine), as well as partnership with the former ProStor for RDX and having acquired some of the assets of ProStor namely their RDX based InifiVault storage appliance. Imation has also been involved in some other things including USB and other forms of flash-based solid state devices (SSD), as well as a couple of years (2007) they launched cloud backup with DataGuard before cloud backup had become a popular buzzword topic.

Imation has also divested parts of its business over past several years including some medical related (X-ray stuff) to Kodak who occupies part of the headquarter building in Oakdale MN, or at least last time I looked when driving by there on way from the airport. They also divested their SAN lab with some of the staff going to Glasshouse and other pieces going to Lion bridge (an independent test lab company). Beyond traditional of data protection, backup/restore and archiving media or mediums from consumer to large-scale enterprise, Imation has also been involved in other areas involving recording. Imation also has done some other recent acquisitions around dedupe (Nine Technologies).

For its part, Nexsan has extended their portfolio from SATA and SAS products, AutoMaid Intelligent Power Management (IPM) which gives benefits of variable power and performance without the penalties of first generation MAID type products. Read more about IPM and related themes here, here and here. Nexsan also supports NAS and iSCSI solutions in addition to their archive and content or object storage focused Assureon product they bought a few years ago.

This is a good acquisition for both companies as it gives Imation a new set of products to sell into their existing accounts and channels. It also can leverage Nexsan’s channel and solution selling skills giving them (Nexsan) a bigger brand and large parent for credibility (not that they did not have that in the past).

Here are is a link to a piece done by Dave Raffo that includes some comments and perspectives from me. To say that the synergy here is about archiving or selling SSD or storage would be too easy and miss a bigger potential. That potential is Imation has been in the business of selling consumable accessories for protecting and preserving data. Notice I said consumable accessories which in the past has meant manufacturing consumable media (e.g. Floppy disks or discs, CD, DVDs, magnetic tapes) as well as partnering around flash and HDDs.

In many environments from small to large to super-sized cloud and service providers, some types of storage systems including some of those that Nexsan sells can be considered a consumable media or medium taking over the role that tape, CDs or DVDs have been used in the pat. Instead of using tape or CDs or DVDs to protect the HDDs and SSDs based data, HDD based solutions are being used for disk-to-disk (D2D) protection (part of modernizing data protection). D2D is being done as appliances, or in conjunction with cloud and object storage system software stacks such as OpenStack swift, Basho Riak CS, CloudStack, Cleversafe, Ceph, Caringo and a list of others, in addition to appliances such as EMC ATMOS among others than can support 3rd party storage device as consumable mediums. Keep in mind that there is no such thing as a data or information recession, and people and data are living longer and getting larger, both for big data and little data.

The big if in this acquisition which IMHO is a fair price for both parties based on realistic valuations is if they can collective execute on it. This means that Imation and Nexsan need to leverage each other’s strengths, address any weakness, close gaps and expand into each other’s markets, channels and sell the entire portfolio as opposed to becoming singular focused on a particular area tool or technology. If Imation can execute on this and Nexsan leverages their new parent, the result should be moving from the roughly $85M USD sales to $100M+ then $125M then $150M and so forth over the next couple of years.

Even if Imation keeps maintains revenues or a slight increase, which would also be a good deal for them, granted the industry pundits may not agree, so let us see where this is in a few years. However if Imation can grow the Nexsan business, then it would become a very good deal. Thus, IMHO the price valuation for the deal has the risk built into, something like when NetApp bought the Engenio business unit from LSI back in 2011 for about $480M USD. At that time, Engenio was doing about $705M USD in revenue and seen by many industry pundits as being on the decline, thus a lower valuation. For its part, NetApp, has been executing maintaining the revenue of that business unit with some expansion, thus their execution so far is being rewarding for taking the risk.

Let us see if Imation can do the same thing.

Now, does that mean that Nexsan was the last of the independent storage vendors left?

Hardly, after all there is still Xiotech, excuse me, Xio as they changed their name as part of a repackaging, relaunch and downsizing. There is DotHill who supplies partners such HP, or Dothills former partner supplier InfoTrend. If you are an Apple fan then you might know about Promise, if not, you should. Lets not forget about Data Direct Networks (DDN) that is still independent and at around $200M (give or take several million) in revenue, are very much still around.

How about Xyratex, sure they make the enclosures and appliances that many others use in their solutions, however they also have a storage solutions business focused on scale out, clustered and grid NAS based on Lustre. There are some others that I am drawing a blank on now (if you read this and are one of them, chime in) in addition to all the new or current generation of startups (you can chime in as well to let people know who you are to be bought).

There is still consolidation taking place, both of smaller vendors by mid-sized vendors, mid-sized vendors by big vendors, big vendors by mega vendors, and startups by established.

Again congratulations to both Imation and Nexsan, let us see who or what is next on the 2013 mergers and acquisition list, as well as who will join the where are they now club.

Disclosure: Nexsan has been a StorageIO client in the past; however, Imation has not been a client, although they have bought me lunch before here in the Stillwater, MN area.

With Imation having their own brand name and identity, not to mention TDK and Memorex, now I have to wonder will Nexsan be real or Memorex or something else? ;)

Ok, nuff said.

Cloud conversations: Gaining cloud confidence from insights into AWS outages (Part II)

StorageIO industry trends cloud, virtualization and big data

This is the second in a two-part industry trends and perspective looking at learning from cloud incidents, view part I here.

There is good information, insight and lessons to be learned from cloud outages and other incidents.

Sorry cynics no that does not mean an end to clouds, as they are here to stay. However when and where to use them, along with what best practices, how to be ready and configure for use are part of the discussion. This means that clouds may not be for everybody or all applications, or at least today. For those who are into clouds for the long haul (either all in or partially) including current skeptics, there are many lessons to be  learned and leveraged.

In order to gain confidence in clouds, some questions that I routinely am asked include are clouds more or less reliable than what you are doing? Depends on what you are doing, and how you will be using the cloud services. If you are applying HA and other BC or resiliency best practices, you may be able to configure and isolate from the more common situations. On the other hand, if you are simply using the cloud services as a low-cost alternative selecting the lowest price and service class (SLAs and SLOs), you might get what you paid for. Thus, clouds are a shared responsibility, the service provider has things they need to do, and the user or person designing how the service will be used have some decisions making responsibilities.

Keep in mind that high availability (HA), resiliency, business continuance (BC) along with disaster recovery (DR) are the sum of several pieces. This includes people, best practices, processes including change management, good design eliminating points of failure and isolating or containing faults, along with how the components  or technology used (e.g. hardware, software, networks, services, tools). Good technology used in goods ways can be part of a highly resilient flexible and scalable data infrastructure. Good technology used in the wrong ways may not leverage the solutions to their full potential.

While it is easy to focus on the physical technologies (servers, storage, networks, software, facilities), many of the cloud services incidents or outages have involved people, process and best practices so those need to be considered.

These incidents or outages bring awareness, a level set, that this is still early in the cloud evolution lifecycle and to move beyond seeing clouds as just a way to cut cost, and seeing the importance and value HA, resiliency, BC and DR. This means learning from mistakes, taking action to correct or fix errors, find and cut points of failure are part of a technology maturing or the use of it. These all tie into having services with service level agreements (SLAs) with service level objectives (SLOs) for availability, reliability, durability, accessibility, performance and security among others to protect against mayhem or other things that can and do happen.

The reason I mentioned earlier that AWS had another incident is that like their peers or competitors who have incidents in the past, AWS appears to be going through some growing, maturing, evolution related activities. During summer 2012 there was an AWS incident that affected Netflix (read more here: AWS and the Netflix Fix?). It should also be noted that there were earlier AWS outages where Netflix (read about Netflix architecture here) leveraged resiliency designs to try and prevent mayhem when others were impacted.

Is AWS a lightning rod for things to happen, a point of attraction for Mayhem and others?

Granted given their size, scope of services and how being used on a global basis AWS is blazing new territory and experiences, similar to what other information services delivery platforms did in the past. What I mean is that while taken for granted today, open systems Unix, Linux, Windows-based along with client-server, midrange or distributed systems, not to mention mainframe hardware, software, networks, processes, procedures, best practices all went through growing pains.

There are a couple of interesting threads going on over in various LinkedIn Groups based on some reporters stories including on speculation of what happened, followed with some good discussions of what actually happened and how to prevent recurrence of them in the future.

Over in the Cloud Computing, SaaS & Virtualization group forum, this thread is based on a Forbes article (Amazon AWS Takes Down Netflix on Christmas Eve) and involves conversations about SLAs, best practices, HA and related themes. Have a look at the story the thread is based on and some of the assertions being made, and ensuing discussions.

Also over at LinkedIn, in the Cloud Hosting & Service Providers group forum, this thread is based on a story titled Why Netflix’ Christmas Eve Crash Was Its Own Fault with a good discussion on clouds, HA, BC, DR, resiliency and related themes.

Over at the Virtualization Practice, there is a piece titled Is Amazon Ruining Public Cloud Computing? with comments from me and Adrian Cockcroft (@Adrianco) a Netflix Architect (you can read his blog here). You can also view some presentations about the Netflix architecture here.

What this all means

Saying you get what you pay for would be too easy and perhaps not applicable.

There are good services free, or low-cost, just like good free content and other things, however vice versa, just because something costs more, does not make it better.

Otoh, there are services that charge a premium however may have no better if not worse reliability, same with content for fee or perceived value that is no better than what you get free.

Additional related material

Some closing thoughts:

  • Clouds are real and can be used safely; however, they are a shared responsibility.
  • Only you can prevent cloud data loss, which means do your homework, be ready.
  • If something can go wrong, it probably will, particularly if humans are involved.
  • Prepare for the unexpected and clarify assumptions vs. realities of service capabilities.
  • Leverage fault isolation and containment to prevent rolling or spreading disasters.
  • Look at cloud services beyond lowest cost or for cost avoidance.
  • What is your organizations culture for learning from mistakes vs. fixing blame?
  • Ask yourself if you, your applications and organization are ready for clouds.
  • Ask your cloud providers if they are ready for you and your applications.
  • Identify what your cloud concerns are to decide what can be done about them.
  • Do a proof of concept to decide what types of clouds and services are best for you.

Do not be scared of clouds, however be ready, do your homework, learn from the mistakes, misfortune and errors of others. Establish and leverage known best practices while creating new ones. Look at the past for guidance to the future, however avoid clinging to, and bringing the baggage of the past to the future. Use new technologies, tools and techniques in new ways vs. using them in old ways.

Ok, nuff said.

Cloud conversations: Gaining cloud confidence from insights into AWS outages

StorageIO industry trends cloud, virtualization and big data

This is the first of a two-part industry trends and perspectives series looking at how to learn from cloud outages (read part II here).

In case you missed it, there were some public cloud outages during the recent Christmas 2012-holiday season. One incident involved Microsoft Xbox (view the Microsoft Azure status dashboard here) users were impacted, and the other was another Amazon Web Services (AWS) incident. Microsoft and AWS are not alone, most if not all cloud services have had some type of incident and have gone on to improve from those outages. Google has had issues with different applications and services including some in December 2012 along with a Gmail incident that received covered back in 2011.

For those interested, here is a link to the AWS status dashboard and a link to the AWS December 24 2012 incident postmortem. In the case of the recent AWS incident which affected users such as Netflix, the incident (read the AWS postmortem and Netflix postmortem) was tied to a human error. This is not to say AWS has more outages or incidents vs. others including Microsoft, it just seems that we hear more about AWS when things happen compared to others. That could be due to AWS size and arguably market leading status, diversity of services and scale at which some of their clients are using them.

Btw, if you were not aware, Microsoft Azure is more than just about supporting SQLserver, Exchange, SharePoint or Office, it is also an IaaS layer for running virtual machines such as Hyper-V, as well as a storage target for storing data. You can use Microsoft Azure storage services as a target for backing up or archiving or as general storage, similar to using AWS S3 or Rackspace Cloud files or other services. Some backup and archiving AaaS and SaaS providers including Evault partner with Microsoft Azure as a storage repository target.

When reading some of the coverage of these recent cloud incidents, I am not sure if I am more amazed by some of the marketing cloud washing, or the cloud bashing and uniformed reporting or lack of research and insight. Then again, if someone repeats a myth often enough for others to hear and repeat, as it gets amplified, the myth may assume status of reality. After all, you may know the expression that if it is on the internet then it must be true?

Have AWS and public cloud services become a lightning rod for when things go wrong?

Here is some coverage of various cloud incidents:

The above are a small sampling of different stories, articles, columns, blogs, perspectives about cloud services outages or other incidents. Assuming the services are available, you can Google or Bing many others along with reading postmortems to gain insight into what happened, the cause, effect and how to prevent in the future.

Do these recent incidents show a trend of increased cloud outages? Alternatively, do they say that the cloud services are being used more and on a larger basis, thus the impacts become more known?

Perhaps it is a mix of the above, and like when a magnetic storage tape gets lost or stolen, it makes for good news or copy, something to write about. Granted there are fewer tapes actually lost than in the past, and far fewer vs. lost or stolen laptops and other devices with data on them. There are probably other reasons such as the lightning rod effect given how much industry hype around clouds that when something does happen, the cynics or foes come out in force, sometimes with FUD.

Similar to traditional hardware or software based product vendors, some service providers have even tried to convince me that they have never had an incident, lost or corrupted or compromised any data, yeah, right. Candidly, I put more credibility and confidence in a vendor or solution provider who tells me that they have had incidents and taken steps to prevent them from recurring. Granted those steps might be made public while others might be under NDA, at least they are learning and implementing improvements.

As part of gaining insights, here are some links to AWS, Google, Microsoft Azure and other service status dashboards where you can view current and past situations.

What is your take on IT clouds? Click here to cast your vote and see what others are thinking about clouds.

Ok, nuff said for now (check out part II here )

Disclosure: I am a customer of AWS for EC2, EBS, S3 and Glacier as well as a customer of Bluehost for hosting and Rackspace for backups. Other than Amazon being a seller of my books (and my blog via Kindle) along with running ads on my sites and being an Amazon Associates member (Google also has ads), none of those mentioned are or have been StorageIO clients.

The Human Face of Big Data, a Book Review

The Human Face of Big Data, a Book Review

My copy of the new book The Human Face of Big Data created by Rick Smolan and Jennifer Erwitt arrived yesterday compliments of EMC (the lead sponsor). In addition to EMC, the other sponsors of the book are Cisco, VMware, FedEx, Originate and Tableau software.

To say this is a big book would be an understatement, then again, big data is a big topic with a lot of diversity if you open your eyes and think in a pragmatic way, which once you open and see the pages you will see. This is physically a big book (11x 14 inches) with lots of pictures, texts, stories, factoids and thought stimulating information of the many facets and dimensions of big data across 224 pages.

While Big Data as a buzzword and industry topic theme might be new, along with some of the related technologies, techniques and focus areas, other as aspects have been around for some time. Big data means many things to various people depending on their focus or areas of interest ranging from analytics to images, videos and other big files. A common theme is the fact that there is no such thing as an information or data recession, and that people and data are living longer, getting larger, and we are all addicted to information for various reasons.

Big data needs to be protected and preserved as it has value, or its value can increase over time as new ways to leverage it are discovered which also leads to changing data access and life cycle patterns. With many faces, facets and areas of interests applying to various spheres of influence, big data is not limited to programmatic, scientific, analytical or research, yet there are many current and use cases in those areas.

Big data is not limited to videos for security surveillance, entertainment, telemetry, audio, social media, energy exploration, geosciences, seismic, forecasting or simulation, yet those have been areas of focus for years. Some big data files or objects are millions of bytes (MBytes), billion of bytes (GBytes) or trillion of bytes (TBytes) in size that when put into file systems or object repositories, add up to Exabytes (EB – 1000 TBytes) or Zettabytes (ZB – 1000 EBs). Now if you think those numbers are far-fetched, simply look back to when you thought a TByte, GByte let alone a MByte was big or far-fetched future. Remember, there is no such thing as a data or information recession, people and data are living longer and getting larger.

Big data is more than hadoop, map reduce, SAS or other programmatic and analytical focused tool, solution or platform, yet those all have been and will be significant focus areas in the future. This also means big data is more than data warehouse, data mart, data mining, social media and event or activity log processing which also are main parts have continued roles going forward. Just as there are large MByte, GByte or TByte sized files or objects, there are also millions and billions of smaller files, objects or pieces of information that are part of the big data universe.

You can take a narrow, product, platform, tool, process, approach, application, sphere of influence or domain of interest view towards big data, or a pragmatic view of the various faces and facets. Of course you can also spin everything that is not little-data to be big data and that is where some of the BS about big data comes from. Big data is not exclusive to the data scientist, researchers, academia, governments or analysts, yet there are areas of focus where those are important. What this means is that there are other areas of big data that do not need a data science, computer science, mathematical, statistician, Doctoral Phd or other advanced degree or training, in other words big data is for everybody.

Cover image of Human Face of Big Data Book

Back to how big this book is in both physical size, as well as rich content. Note the size of The Human Face of Big Data book in the adjacent image that for comparison purposes has a copy of my last book Cloud and Virtual Data Storage Networking (CRC), along with a 2.5 inch hard disk drive (HDD) and a growler. The Growler is from Lift Bridge Brewery (Stillwater, MN), after all, reading a big book about big data can create the need for a big beer to address a big thirst for information ;).

The Human Face of Big Data is more than a coffee table or picture book as it is full of with information, factoids and perspectives how information and data surround us every day. Check out the image below and note the 2.5 inch HDD sitting on the top right hand corner of the page above the text. Open up a copy of The Human Face of Big Data and you will see examples of how data and information are all around us, and our dependence upon it.

How many degrees separate you and your information?
Hardware, Software, what about Valueware?
Changing Lifecycles and Data Footprint Reduction (Data doesnt have to lose value over time)
Garbage data in, garbage information out, big data or big garbage?
Industry adoption vs. industry deployment, is there a difference?
Is There a Data and I/O Activity Recession?
Industry trend: People plus data are aging and living longer
Supporting IT growth demand during economic uncertain times
No Such Thing as an Information Recession

For those who can see big data in a broad and pragmatic way, perhaps using the visualization aspect this book brings forth the idea that there are and will be many opportunities. Then again for those who have a narrow or specific view of what is or is not big data, there is so much of it around and various types along with focus areas you too will see some benefits.

Do you want to play in or be part of a big data puddle, pond, or lake, or sail and explore the oceans of big data and all the different aspects found in, under and around those bigger broader bodies of water.

Bottom line, this is a great book and read regardless of if you are involved with data and information related topics or themes, the format and design lend itself to any audience. Broaden your horizons, open your eyes, ears and thinking to the many facets and faces of big data that are all around us by getting your copy of The Human Face of Big Data (Click here to go to Amazon for your copy) book.

Hardware, Software, what about Valueware?

StorageIO industry trends cloud, virtualization and big data

I am surprised nobody has figured out how to use the term valueware to describe their hardware, software or services solutions, particular around cloud, big data, little data, converged solution stacks or bundles, virtualization and related themes.

Cloud virtualization storage and networking building blocks image
Cloud and virtualization building blocks transformed into Valueware

Note that I’m referring to IT hardware and not what you would usually find at a TrueValue hardware store (disclosure, I like to shop there for things to innovate with and address the non IT to do project list).

Instead of value add software or what might otherwise be called an operating system (OS), or middleware, glue, hypervisor, shims or agents, I wonder who will be first to use valueware? Or who will be the first to say they were the first to articulate the value of their industry unique and revolutionary solution using valueware?

Cloud and convergence stack image from Cloud and Virtual Data Storage Networking Book

For those not familiar, converged solution stack bundles combine server, storage and networking hardware along with management software and other tools in a prepackaged solution from the same or multiple vendors. Examples include Dell VIS (not to be confused with their reference architectures or fish in Dutch), VCE or EMC vBlocks, IBM Puresystems, NetApp FlexPods and Oracle Exaboxes among others.

Converged solution or cloud bundle image from Cloud and Virtual Data Storage Networking Book

Why is it that the IT or ICT (for my European friends) industries are not using valueware?

Is Valueware not being used because it has not been brought to their attention yet or part of anybody’s buzzword bingo list or read about in an industry trade rag (publication) or blog (other than here) or on twitter?

Buzzword bingo image

Is it because the term value in some marketers opinion or view their research focus groups associate with being cheap or low-cost? If that is the case, I wonder how many of those marketing focus groups actually include active IT or ICT professionals. If those research marketing focus groups contact practicing IT or ICT pros, then there would be a lower degree of separation to the information, vs. professional focus group or survey participants who may have a larger degree of separation from practioneers.

Degrees of seperation image

Depending on who uses valueware first and how used, if it becomes popular or trendy, rest assured there would be bandwagon racing to the train station to jump on board the marketing innovation train.

Image and video with audio of train going down the tracks

On the other hand, using valueware could be an innovative way to help articulate soft product value (read more about hard and soft product here). For those not familiar, hard product does not simply mean hardware, it includes many technologies (including hardware, software, networks, services) that combined with best practices and other things to create a soft product (solution experience).

Whatever the reason, I am assuming that valueware is not going to be used by creative marketers so let us have some fun with it instead.

Let me rephrase that, let us leave valueware  alone, instead look at the esteemed company it is in or with (some are for fun, some are for real).

  • APIware (having some fun with those who see the world via APIs)
  • Cloudware (not to be confused with cloud washing)
  • Firmware (software tied to hardware, is it hardware or software? ;) )
  • Hardware (something software, virtualization and clouds run on)
  • Innovationware (not to be confused with a data protection company called Innovation)
  • Larryware (anything Uncle Larry wants it to be)

Image of uncle larry aka Larry Elison taking on whomever or whatever

  • Marketware (related to marketecture)
  • Middleware (software to add value or glue other software together)
  • Netware (RIP Ray Noorda)
  • Peopleware (those who use or support IT and cloud services)
  • Santaware (come on, tis the season right)
  • Sleepware (disks and servers spin down to sleep using IPM techniques)
  • Slideware (software defined marketing presentations)
  • Software (something that runs on hardware)
  • Solutionware (could be a variation of implementation of soft product)
  • Stackware (something that can also be done with Tupperware)
  • Tupperware (something that can be used for food storage)
  • Valueware (valueware.us points to this page, unless somebody wants to buy or rent it ;) )
  • Vaporware (does vaporware actually exist?)

More variations can be added to the above list, for example substituting ware for wear. However, I will leave that up to your own creativity and innovation skills.

Let’s see if anybody starts to use Valueware as part of their marketware or value proposition slideware pitches, and if you do use it, let me know, be happy to give you a shout out.

Ok, nuff said.

Storage comments from the field and customers in the trenches

StorageIO industry trends cloud, virtualization and big data

When I was in Europe presenting some sessions at conferences and doing some seminars last month I meet and spoke with one of the attendees at the StorageExpo Holland event. The persons name (Han Breemer) came up to visit with me after one of my presentations that include SSD is in your future: When, where, with what and how, and Cloud and Virtual Data Storage Networking industry trends and perspectives. Note you can find additional material from various conferences and events on the backup, restore, BC, DR and archiving accessible via the resources menu on the StorageIO web site.

As I always do, I invite attendees to feel free and follow-up via email, twitter, Linked In, Google+ or other venue with questions, comments, discussions and what they are seeing or running into in their environments.

Some of the many different items discussed during my StorageExpo presentations included:

Recently Hans followed up and sent me some comments and asked if I would be willing to share them with others such as who ever happens to read this. I also suggested to Hans that he also start a blog (here is link to his new blog), and that I would be happy to post his comments for others to see and join in the conversation which are shown below.

Hans Breemer wrote:

Hi Greg,

we met each other recently at the Dutch Storage Expo after one of your sessions. We briefly discussed the current trends in the storage market, and the “risks” or “threats” (read: challenges) it means to “us”, the storage guys. Often neglected by the sales guys…

Please allow me a few lines to elaborate a bit more and share some thoughts from the field. :-)

1. Bigger is not better?

Each iteration in the new disk technologies (SATA or SAS) means we get less IOPS for the bucks. Pound for pound that is. Of course the absolute amount of IOPS we can get from a HDD increases all the time. where 175 IOPS was top speed a few years ago, we sometimes see figures close to 220 IOPS per physical drive now. This looks good in the brochure, just as the increased capacity does. However, what the brochure doesn’t tell us that if we look at the IOPS/capacity ratio, we’re walking backwards. a few years ago we could easily sell over 1000 IOPS/TB. Currently we can’t anymore. We’re happy to reach 500 IOPS/TB. I know this has always been like that. However with the introduction of SATA in the enterprise storage world, I feel things have gotten even worse.

2. But how about SSD’s then?

True and agree. In the world of HDD’s growing bigger and bigger, we actually need SSD’s, and this technology is the way forward in an IOPS perspective. SSD’s have a great future ahead of them (despite being with us already for some time). I do doubt that at the moment SSD’s already have the economical ability to fill the gap though. They offer many of thousands of IOPS, and for dedicated high-end solutions they offer what we weren’t able to deliver for decades. More IOPS than you need! But what about the “1000 IOPS/TB” market? Let’s call it the middle market.

3. SSD’s as a lubricant?

You must have heard every vendor about Adaptive Storage Tiering, Auto Tiering etc. All based on the theorem that most of our IO’s come from a relative small disk section. Thus we can improve the total performance of our array by only adding a few percent of SSD. Smart technology identifies the hot tracks on our disks, and promotes these to SSD’s. We can even demote cold tracks to big SATA drives. Think green, think ecological footprint, etc. For many applications this works well. Regular Windows server, file servers, VMWare ESX server actually seems to like adaptive storage tiering ,and I think I know why, a positive tradeoff of using VMDK’s. (I might share a few lines about FAST VP do’s and dont’s next time if you don’t mind)

4. How about the middle market them you might ask? or, SSD’s as a band-aid?

For the middle market, the above developments is sort of disaster. Think SAP running on Sun Solaris, think the average Microsoft SQL Server, think Oracle databases. These are the typical applications that need “middle market” IOPS. Many of these applications have a freakish IO pattern. OLTP during daytime, backup in the evening and batch jobs at night. Not to mention end of month runs, DTA (Dev-Test-Acceptance) streets that sleep for two weeks or are constantly upgraded or restored. These applications hardly benefit from “smart technologies”. The IO behavior is too random, too unpredictable leading to saturated SATA pools, and EFD’s that are hardly doing more IO’s than the FC drives they’re supposed to relief. Add more SSD’s we’re told. Use less SATA we’re told. but it hardly works. Recently we acquired a few new Vmax arrays without EFD or FASTVP, for the sole purpose of hosting these typical middle market applications. Affordable, predictable performance. But then again, our existing Vmax 20k had full size 600GB 15rpm drives, with the Vmax 40k we’re “encouraged” to use small form factor 600GB 10krpm drives. Again a small step backwards?

5. The storage tiering debacle.

Last but not least, some words I’d like to share with you about storage tiering. We’re encouraged (again) to sell storage in different tiers. Makes sense. To some extent it does yes. Host you most IO eager application on expensive, SSD based storage. And host your DTA or other less business critical application on FC or SATA quality HDD’s. But what if the less business critical application needs to be backed up in the evening, and while doing so completely saturates your SATA pool? Or what if the Dev server creates just as many IO’s as the Prod environment does? People don’t seem to care it seems. To have people realize how much IO’s they actually need and use, we are reporting IO graphs for all servers in our environment. Our tiering model is based on IOPS/TB and IO response time.

Tier X would be expensive, offering 800 IOPS/TB @ avg 10ms
Tier Y would be the cheaper option offering 400 IOPS/TB @ avg 15 ms

The next step will be to implement front end controls an actually limit a host to some ceiling. for instance, 2 times the limit described in the tier description. thus allowing for peak loads and backups.

Do we need to? I think so…

Greg, this small message is slowly turning into a plea. And that is actually what it is, a plea to our storage vendors, and to our evangelists. If they want us to deliver, I feel they should talk to us, and listen to us (and you!).

Cheers,

Hans Breemer 

ps, I love my job, this world and my role to translate promises and demands into solutions that work for my customers. I do take care though not to create solution that will not work, despite what the brochure said.

pps, please feel free to share the above if needed.

Here is my response to Hans:

Hello Hans good to hear from you and thanks for the comments.

Great perspectives and in the course of talking with your peers around the world, you are not alone in your thinking.

Often I see disconnects between customers and vendors. Vendors (often driven by their market research) they know what the customer needs and issues are, and many actually do. However I often see a reliance on market research data with many degrees of separation as opposed to direct and candied insight. Likewise some vendors spend more time talking about how they listen to the customer vs. how time they actually do so.

On the other hand, I routinely see customers fall into the trap of communicating wants (nice to haves) instead of articulating needs (what is required). Then there is confusing industry adoption with customer deployment, not to mention concerns over vendor, technology or services lock-in.

Hope all else is well.

Cheers

HPs big December 3rd storage announcement

HP has been talking and promoting for several weeks (ok, months) their upcoming December 3rd storage announcements from the HP discovery event in Frankfurt Germany.

Well its now afternoon which means the early Monday morning December 3rd embargos have been lifted so I can now talk about what HP shared last Friday about todays announcements. Basically what I received was a series of press releases as well link to their updated web site providing information about todays announcements.

HP has enhanced the 3PAR aka P10000 with new models including for entry-level, as well as for higher performance enterprises needs. This also should beg the question for many longtime EVA (excuse me, P6000) customers, have they hit the end of the line? For scale out storage, HP has the StoreAll solutions (think about products formerly marketed as certain X9000 models based on Ibrix) with enhancements for analytics, bulk and various types of big data. In addition HP has enhanced its backup and recovery capabilities and Dedupe products including integration with Autonomy (here and here) along with capacity on demand services.

New 3PAR (P10000 models)

New StoreAll storage system

From the surface and what I have been able to see so far, looks like a good set of incremental enhancements from HP. Not much else to say until I can get some time to dig around deep to see what can be found on more details, however check out Calvin Zito (aka @hpstorageguy) the HP storage blogger who should have more information from HP.

Ok, nuff said (for now).

Ceph Day Amsterdam 2012 (Object and cloud storage)

StorageIO industry trends cloud, virtualization and big data

Recently while I was in Europe presenting some sessions at conferences and doing some seminars, I was invited by Ed Saipetch (@edsai) of Inktank.com to attend the first Ceph Day in Amsterdam.

Ceph day image

As luck or fate would turn out, I was in Nijkerk which is about an hour train ride from Amsterdam central station plus a free day in my schedule. After a morning train ride and nice walk from Amsterdam Central I arrived at the Tobacco Theatre (a former tobacco trading venue) where Ceph Day was underway, and in time for lunch of Krokettens sandwich.

Attendees at Ceph Day

Lets take a quick step back and address for those not familiar what is Ceph (Cephalanthera) and why it was worth spending a day to attend this event. Ceph is an open source distributed object scale out (e.g. cluster or grid) software platform running on industry standard hardware.

Ceph is used for deploying object storage, cloud storage and managed services, general purpose storage for research, commercial, scientific, high performance computing (HPC) or high productivity computing (commercial) along with backup or data protection and archiving destinations. Other software similar in functionality or capabilities to Ceph include OpenStack Swift, Basho Riak CS, Cleversafe, Scality and Caringo among others. There are also the tin wrapped software (e.g. appliances or pre-packaged) solutions such as Dell DX (Caringo), DataDirect Networks (DDN) WOS, EMC ATMOS and Centera, Amplidata and HDS HCP among others. From a service standpoint, these solutions can be used to build services similar Amazon S3 and Glacier, Rackspace Cloud files and Cloud Block, DreamHost DreamObject and HP Cloud storage among others.

Ceph cloud and object storage architecture image

At the heart of Ceph is RADOS a distributed object store that consists of peer nodes functioning as object storage devices (OSD). Data can be accessed via REST (Amazon S3 like) APIs, Libraries, CEPHFS and gateway with information being spread across nodes and OSDs using a CRUSH based algorithm (note Sage Weil is one of the authors of CRUSH: Controlled, Scalable, Decentralized Placement of Replicated Data). Ceph is scalable in terms of performance, availability and capacity by adding extra nodes with hard disk drives (HDD) or solid state devices (SSDs). One of the presentations pertained to DreamHost that was an early adopter of Ceph to make their DreamObjects (cloud storage) offering.

In addition to storage nodes, there are also an odd number of monitor nodes to coordinate and manage the Ceph cluster along with optional gateways for file access. In the above figure (via DreamHost), load balancers sit in front of gateways that interact with the storage nodes. The storage node in this example is a physical server with 12 x 3TB HDDs each configured as a OSD.

Ceph dreamhost dreamobject cloud and object storage configuration image

In the DreamHost example above, there are 90 storage nodes plus 3 management nodes, the total raw storage capacity (no RAID) is about 3PB (12 x 3TB = 36TB x 90 = 3.24PB). Instead of using RAID or mirroring, each objects data is replicated or copied to three (e.g. N=3) different OSDs (on separate nodes), where N is adjustable for a given level of data protection, for a usable storage capacity of about 1PB.

Note that for more usable capacity and lower availability, N could be set lower, or a larger value of N would give more durability or data protection at higher storage capacity overhead cost. In addition to using JBOD configurations with replication, Ceph can also be configured with a combination of RAID and replication providing more flexibility for larger environments to balance performance, availability, capacity and economics.

One of the benefits of Ceph is the flexibility to configure it how you want or need for different applications. This can be in a cost-effective hardware light configuration using JBOD or internal HDDs in small form factor generally available servers, or high density servers and storage enclosures with optional RAID adapters along with SSD. This flexibility is different from some cloud and object storage systems or software tools which take a stance of not using or avoiding RAID vs. providing options and flexibility to configure and use the technology how you see fit.

Here are some links to presentations from Ceph Day:

Ceph in the Cloud by Wido den Hollander
DreamObjects: Cloud Object Storage with Ceph by Ross Turk

Presentations during ceph day

While at Ceph day, I was able to spend a few minutes with Sage Weil Ceph creator and founder of inktank.com to record a pod cast (listen here) about what Ceph is, where and when to use it, along with other related topics. Also while at the event I had a chance to sit down with Curtis (aka Mr. Backup) Preston where we did a simulcast video and pod cast. The simulcast involved Curtis recording this video with me as a guest discussing Ceph, cloud and object storage, backup, data protection and related themes while I recorded this pod cast.

One of the interesting things I heard, or actually did not hear while at the Ceph Day event that I tend to hear at related conferences such as SNW is a focus on where and how to use, configure and deploy Ceph along with various configuration options, replication or copy modes as opposed to going off on erasure codes or other tangents. In other words, instead of focusing on the data protection protocol and algorithms, or what is wrong with the competition or other architectures, the Ceph Day focused was removing cloud and object storage objections and enablement.

Where do you get Ceph? You can get it here, as well as via 42on.com and inktank.com.

Thanks again to Sage Weil for taking time out of his busy schedule to record a pod cast talking about Ceph, as well 42on.com and inktank for hosting, and the invitation to attend the first Ceph Day in Amsterdam.
